To all whom it may concern:

Be it known that I, GEORGE W. Hrmnnm, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have invented a certain new and useful Printing Ink, of which the following. is a specification.

The invention relates to rintin ink and particularly to the base veliicle or carrier to which igmen 1s a e o produce the finished in The invention relates further to a printing ink base made from petroleum residium, commercially termed fuel oil, or hea crude oil having a gravity of II dbout -17 Eaume with a flash point of 150 F. and containing about of asphaltum. An object of the invention is to provide a rinting ink on which a film or skin will not orm on exposure of the ink to the air.

Another object of the invention is to provide a quick drying residium base ink.

A further object of the invention is to rovide a process of making the ink of my invention.

The invention possesses other advantageous features, some of which, with the foreing will be set forth at length in the folowin description where I shall outline in full, t e preferred form of the ink of my invention and the method of making the same. In accordance with my invention I mix the residium, a material or materials which serve to deodorize or partially deodorize, or desulphurize or partially desulphurize the .35 residium, a. material or materials which react to form a sludge or an imperfect sogp which imparts the required body to the i and preferably serve as driers. These ingredients are mixed 0) together and heated to drive ofl' any contamed water and to cause the necessary reactions to go forward to produce the desired base. To this base I then add a material or materials which act as further driers and the desired pigment or dye. The material which -I employ to deodorize the residium 1s referably a mineral salt, such as copp er siphate, chloride or nitrate, or a minera base such as co er oxlde CuO either (11 or mixed 1n wa er, w 10 ac s upon or absorbs the sulphides present in the oil becommg an impure copp e r sulphide; the acids in the resin will act par 1a y on this oxide thereby causin solut1on in the process. The materials emp-0yed to produce the sludge or Application filed August 7, 1922. Serial m.

.which the driers and i a material or materials which imperfect soap are preferably resin, or resmous materia s or resinates of minerals and an alkali, such as sodium li drate. I be resin is melted in the oil and the sodium hydrate reacts with the resin and oil. The drier added to the mass at this time is preferably a calcium or ma esium chloride, with or withou water. To this mixture I preferably add water, either as free water or as the solvent for one or more of the added materials, so that suflicient water is present to insure the completion of the desired reaction. This mixture is then heated to dehydration or substantial dehydration, at which time it becomes a deodorized conglomerate sludge. To this sludge the desired driers and i 'ments are a e I ave produced very satisfactory ink from the following materials in the proportions stated:

. Per cent. Residium scwes; Resin ltolO Co per nitrate f C'a cium chloride 1 Sodium h drate 1 Sodium si icate. 1 Water, sufficient quantity.

These ingredients are mixed and heated to dehydration to form the ink base after cuts are added. I have obtalned satisfactory results with an ink consisting of:

Per cent.

Base 65 9o Linoleate of lead 4 Japan drier 6 Pigment 25 While I have specified certain ingredients which enter into the ink of my invention, it is to be understood that their equivalents may be used with satisfactory results. For instance, in place of resin I may use other soap making materials such as oils, fats or waxes.

'I claim:

1. A printing ink base comprismg fuel oil, a deodorant comprising a copper salt, and an imperfect soap; 2. A printing ink ase comprismg fuel oil, a deodorant comprising a copper salt, a resinous material and a material which reacts therewith to form an imperfect soap.

3. A printing ink base comprising fuel 61min oil, a salt of copper, rosin, an alkali which reacts with the rosin to form a sludge, and a drier.

4. A printing ink base comprising a deb?- drated mixture of fuel oil, a copper sa t, rosin, and sodium hydrate.

5. A printing ink base comprising a dehydrated sludge comprising fuel oil, a copper 'salt rosin, sodium 11 drate, and a drier.

6. A printing ink ase comprising a dehydrated mixture of fuel oil, a copper salt deodorant, rosin, an alkali which reacts with the rosin to form a sludge, and a drier.

7. The process of making printing ink base-which comprises heating a mixture of fuel oil and a deodorant with an imperfect soap.

8. The process of making printing ink which comprises heating a mixture of fuel oil, a' deodorant, and an imperfect soap to form a base, and adding a drier and pigment to said base. I

9. A printing ink base comprising the following ingredients: fuel oil, rosin, copper nitrate, calcium chloride sodium hydrate,

sodium silicate, and water.

10. A printing ink com rising fuel oil, rosin, copper nitrate, ca cium chloride, sodium hydrate, sodium silicate, linoleate of lead,-a pigment, a drier, and water.

11. A printing ink base comprising the following ingredients in the proportions mentioned:

Per cent. Fuel oil 86 to 95% 1 to 10 (oppcr nitrate i 12. A printing ink comprising the followin ingredients in the proportions state s s l D m: ..I er Watermmdentqmtity.

In testimony whereof, I, have hereunto set In hand.
